Procedure
To a stirred solution of Example 11 (0.115 g, 0.29 mmol) in DMF (2 mL) was added pentafluorophenol (0.064 g, 0.35 mmol), DIPEA (0.100 mL, 0.57 mmol) and EDC (0.072 g, 0.37 mmol). The reaction mixture was stirred at r.t. for 48 h. Dimethylamine (40% w/v in water, 5 mL) was added and the reaction mixture stirred for 16 h at r.t. The reaction mixture was concentrated in vacuo. DCM (5 mL) and water (5 mL) were added. The aqueous layer was extracted with DCM (2×3 mL). The combined organic fractions were washed with water (3×15 mL), dried (Na2SO4), filtered and the solvent evaporated in vacuo. The residue was purified by preparative HPLC (Method 6) to give the title compound (0.040 g, 45%) as a white solid. δH (CD3OD) 8.07 (1H, s), 7.42 (1H, m), 7.25-7.19 (2H, m), 4.39-4.29 (1H, m), 4.14-3.99 (1H, m), 3.88 (1H, d, J 11.9 Hz), 3.72-3.51 (4H, m), 3.42 (1H, dd, J 13.8 Hz and J 10.2 Hz), 3.19-3.03 (7H, m), 2.57 (3H, s), 2.43 (3H, s). Exchangeable proton not observed. LCMS (ES+) 427.0 (M+H)+, RT 2.59 minutes (Method 2).
